You will go to State Prison not Jail, Jail is a county thing and Prison is state or federal,
First offense?
19, The DA was of course a prick to nail you with all those charges, you will probably go to a minimum security prison, or a work farm.
Safer and better than a State Prison.
If the DA ask for three years, you will get two and serve 6 months to one year. Minimum security and work farms are not summer camp, but you are less likely to get raped or murdered.
Prisons in California are segregated, Blacks, Hispanics, Arian brothers and older guys are all kept separate. Everyone has there own Shot Guard.
If they weren’t everyone would kill everyone else, I am not kidding.
I don’t know about Pennsylvania, but there are no weights in California Prison, and you can’t get gear, drugs and booze yes but no gear, go figure.
Sounds like you are white guy, so guess who you will want to hang with, DON’T act scared or tuff, just be as relaxed as possible, you will find a grove and be fine.
I was in last year 2nd time, for possession and loaded firearms, I am only 5’5” 185 on gear most of the time, Then maybe 190-195, middle of a serious cycle. I am 56 years old, and for the first few months (don’t know really how long) I was with southsiders, Hispanic gang here in LA and I think everywhere, Most of the kids were in there early 20’s just gang bangers. They were cool, then I finished in the hospital ward, was sick, thank you Jesus.
Don’t worry, get someone to send you a lot of books. Nothing to do, boredom will drive you do want drugs.
